Hack saw handle



Patented Sept. 17, 1935 UNITED STATES PATENT OFFICE HACK SAW HANDLE Application November 2, 1934, Serial No. 751,153

1 Claim.

My invention relates to handles for hacksaws 'and the like.

The main object is to provide a light, but strong handle which can be made cheaply.

Another object is to provide a handle which although suiiiciently rigid is nevertheless resilient and therefore more comfortable to hold and operate.

I therefore form the handle out of strip steel of U-shaped cross section and secure the ends to a part of the frame bar.

Fig. 1 is a perspective view of a hacksaw handle involvingl my invention and showing it in conjunction with the remaining parts of the frame in dotted lines.

Fig. 2 is a side view of the handle.

Fig. 3 is an end View of the handle.

Fig. 4 is a cross sectional view along line 4-4 of Fig. 2.

Fig. 5 is a sectional view showing a modification.

The invention is shown applied to an adjustable frame formed of two parts, one part being shown dotted and the part involving the invention being shown in full lines. The L-shaped frame part has a main upper arm 6 and an end member 1 formed from a flat bar or rod.

The loop-like handle has its ends 8 and 9 secured to the frame part. This handle has the upper part I0, the rear part Il, the front part I2 and the connecting curved end I3 all formed of a single piece of strip steel grooved or corrugated to strengthen it and to form a smooth and comfortable grip. Preferably this is made resilient so that although strong enough for the work it has to perform, it will yield slightly in the grip of the hand and thus avoid fatigue.

The end 8 is closed tight on to the arm 6 and Welded in place at I4. The other end 9 is split so as to embrace both sides of the bar 'l and is welded in place at l5. These ends are preformed in the press so that they can be readily applied to the frame bar. The parts are so shaped as to apply the necessary force in the most effective manner. Note that the upper part l0 of the handle is in effect an extension of the arm 6 and is in alignment with this main upper arm.

In some cases it may be desirable to reinforce the handle for instance by a tie member I8 which may be welded or otherwise secured in place be- 15 tween the flanges.

I claim:

Handle structure for a hack saw having a substantially L-shaped frame member, said handle comprising a sheet metal strip, said strip being bent lto U-shaped cross section throughout its length and. bent to form a loop, a portion of said loop constituting an extension in alignment with one of the arms of said L-frame, the end of said strip handle adjacent said aligned extension being bent so that the U-shaped contour closely fits the upper edge of the L-arm with which the loop portion is aligned, the other end of said strip handle being slotted at the bight of the U and bent so that the legs of the U closely fit the sides of the other L-arm of said frame, and means for rigidly securing the fitted ends of said strip handle to said frame.
